SAFETY ATTACHMENT FOR ANCHORS.

SPECIFICATION forming part of Letters Patent No. 372,938, dated November8, 1887.

Application filed March 14, 1887. Serial No. 230,844.

To all whom. it may concern.-

Be it known that 1, N ELsoN SMITH,ofSmithville South, in the county ofQueens and State of New York, have invented a new and Improved SafetyAttachment for Anchors, of which the following is a full, clear, andexact description.

My invention relates to a safety attachment for anchors, and has for itsobject to provide a devicecapable of ready attachment to an ordinaryanchor, whereby when the anchor is fixed in the bottom it cannot bedetached by entanglement with the cable, and wherein the said anchor maybe cat-headed in the usual manner without inconvenience.

The invention consists in pivoting a triangular frame to the shank of ananchor between the flukes, so constructed that it will guide the cableclear of the non-embedded fluke without regard to the position of theship, as will be hereinafter more specifically set forth, and pointedout in the claims. I

Referenceis to be had to the accompanying drawing, forming a part ofthis'specification, in which the figure represents a perspective View ofan anchor having my improvement applied thereto.

Vessels are often endangered when riding at anchor by the entanglementof the cable with the exposed fluke of the embedded anchor, whichresults in the detachment of said anchor and the consequent drifting ofthe vessel, whereupon serious damage may result before the cable can becleared and another holding found. To overcome this objection atriangular frame, A, is pivoted'at its apex about centrally the shank Aof the anchor, the base whereof is adapted to extend downward andreciprocate between the flukes a. The frame A is constructed of twotriangular arms, B B, upon opposite sides of the shank, held at aninclination outward in opposite directions by a series of horizontalbars or plates, 0, as shown. Inner guide-bars, D, are also provided theframe, which bars are made integral with (No model.)

the triangular frame, are preferably made with a rounding surface, andthe said base-bars extend at such a distance downward as to be under allconditions below the plane of the under side of the fiukes, and theframe is extended sufficiently at the base to permit the aforesaidbase-bars to project beyond the un der edge of said flukes.

In operation, when the anchor is dropped and one fluke engages thebottom, the frame A is crowded by contact with said bottom over towardand in near engagement with the exposed fluke, as illustrated. In theevent the cable should foul the anchor thus protected it will beimpossible for an entanglementto result, as the cable can at nopointobtain a hold, but will engage either one bar, bb,or both, and beguided thereby over the fluke and freed.

- It will be observed that the attachment in no manner interferes withcatting the anchor, as either fluke may be as readily caught by thecat-hook as in the old form of anchor.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an anchor attachment, the combination, with the shank A andparallel triangular and outwardly-inclined arms BB, pivoted uponopposite sides of said shank between the iiukes a, of inner horizontalguide-bars, D D, integral with said arms, adapted to limit the outwardinclination thereof, substantially as shown and described, and for thepurpose herein set forth.

2. In an anchor attachment, the combination,with the shank A of ananchor, ofa frame, A, pivoted at its'apex thereto, consisting of theparallel side arms, B B, adapted to extend downward between and belowthe flukes or, inner horizontal guide-bars, D D, integral with said sidearms, and means for retaining the said arms atan inclination outward inopposite directions, substantially as shown and described,and for thepurpose herein set forth.
